  Google Vertex AI inference provider enables you to use Google's Gemini models through Google Cloud's Vertex AI platform, providing several advantages:

  • Enterprise-grade security: Uses Google Cloud's security controls and IAM
  • Better integration: Seamless integration with other Google Cloud services
  • Advanced features: Access to additional Vertex AI features like model tuning and monitoring
  • Authentication: Uses Google Cloud Application Default Credentials (ADC) instead of API keys

  Configuration:
  - Set VERTEX_AI_PROJECT environment variable (required)
  - Set VERTEX_AI_LOCATION environment variable (optional, defaults to us-central1)
  - Use Google Cloud Application Default Credentials or service account key

  Authentication Setup:
  Option 1 (Recommended): gcloud auth application-default login
  Option 2: Set GOOGLE_APPLICATION_CREDENTIALS to service account key path

  Available Models:
  - vertex_ai/gemini-2.0-flash
  - vertex_ai/gemini-2.5-flash
  - vertex_ai/gemini-2.5-pro
